Dear Li Nah,
A Tao Hua (peach blossom) does not necessarily mean adultery. It could also mean, he suddenly falls deeply in love with you. Tao Hua basically represents attractiveness or being attracted to something.
All you have to do, is to ensure YOU are attractive both internally and externally. Remember - your husband is not 'broken' - you don't have to go about life trying to FIX him.
Be happy.
Warm Regards,
JY
